(
MDPI
, 2021 , Article)
Atmospheric aerosols and dust have become a challenge for urban air quality. The pre-sented study quantified seasonal spatio-temporal variations of aerosols, tropospheric ozone, and dust over the Middle East (ME) for the ...
The effect of graphene structural integrity on the power factor of tin selenide nanocomposite
(
Elsevier
, 2021 , Article)
Tin selenide graphene nanocomposites (SnSe/GNPs) were fabricated with high-energy ball milling and hot pressing by varying the milling time of graphene. The effect of ball milling time on the graphene integrity and the ...
